As discussed in the tenth and eleventh quarterly reports, the advantages of the Focus Reflex Modulation FRM gun design were not compatible with good oxide cathode life when used in a conventional display tube. Consequently, a pilot run change was made whereby the FRM gun design could be utilized in a high resolution cathode-ray tube with a dispenser cathode. The dispenser cathode is capable of withstanding the ion bombardment produced by these systems. Author
